12V Continuous Duty Glow Plug Relay

The Stancor 586-902 Monster Glow Plug Relay (GPR) is an aftermarket upgrade designed to provide a more reliable and powerful solution for diesel engine cold starts. Originally intended for demanding applications in large sound studio amplifiers, this 12-volt continuous duty relay boasts a 200-amp continuous and 600-amp inrush contact rating, ensuring consistent voltage delivery to the glow plugs, even in harsh conditions. This relay is presented as a superior replacement for stock GPRs, offering increased longevity and better performance, especially for cold climate diesel trucks, work trucks, and tow rigs. Users have reported significant satisfaction, with some installations dating back over six years and continuing to perform well. It is crucial to note that this relay is not compatible with Late 99-03 California emissions trucks or Excursions that utilize a Glow Plug Control Module instead of a GPR. Verification of your vehicle's system before ordering is recommended. When tightening the small terminal lugs, caution is advised: only tighten enough to seat the nut on the lock washer, as overtightening can cause the lug to shear off, and broken terminals are not covered by warranty. Relays are also non-returnable once opened. Recommended torque specifications are 60 inch-lbs. maximum for the contact terminals and 12-18 inch-lbs. maximum for the coil terminals. This product is specifically recommended for Ford 7.3L Powerstroke Diesel Engines from model years 1994.5 to 2003.
